GENERAL DESCRIPTION
Ultra low power, compact and low cost 2.4GHz transceiver The nRF24L01+ The nRF24L01 is a unique wireless solution for compact, battery operated applications with stringent requirements on battery lifetime and cost. The transceiver operates in the license free worldwide 2.4GHz ISM band.
It is specifically designed for two types of application: PC peripherals and ultra low power applications such as sports and wellness sensors. For PC peripherals such as wireless mice, keyboards and media center remotes it enables high performance and long battery life at a low solution cost. For sensor applications the ultra low power consumption and advanced power management enables battery lifetimes up to several years on a coin cell battery.
Smooth transition from nRF24L01
Improved co-existence performance and longer range The nRF24L01+ is mechanically, functional and electrical drop in compatible with the nRF24L01. In addition it offers significant improvements on co-existence performance with wide band inference sources like WiFi compared to nRF24L01. It also adds a 250 kbps air-data rate mode offering -94dBm sensitivity for longer range operation.
Compact, highly integrated low cost solution
Compact 4x4mm package, low cost external BOM The nRF24L01+ integrates a complete 2.4GHz RF transceiver, an RF synthesizer, and full baseband logic including the unique Enhanced ShockBurst" hardware link layer, advanced power management and a high-speed SPI for the host controller interface. No external loop filters, resonators or VCO varactor diodes are required, only a low cost ±60ppm 16MHz crystal, matching circuitry and the antenna.
Ultra low power consumption
A unique combination of high air data rate and advanced power management The nRF24L01+ has a unique combination of four features that enable the implementation of ultra-low power wireless connectivity: - Sub 13mA TX and RX active currents that permit coin- cell battery operation - Advanced power management with power saving idle modes combined with rapid active mode start-up from idle - High 2 Mbps on-air data rate that allows the transceiver to minimize the time it spends in the relatively more power consuming active mode for a given effective data rate - Enhanced ShockBurstTM link layer minimizes processing load on the host microcontroller reducing average current consumption
